The Incorporated Society of British Advertisers (ISBA) acts as the voice of British advertisers, by offering expertise, unique membership advantages, cost savings and campaigning for advertiser freedoms.

Founded almost 100 years ago, ISBA represents £6.5 billion of marketing communications spend and is the single body, within the UK, to represent advertisers' interests across all marketing communication disciplines. 

ISBA is the advertiser’s sole representative on the Committee of Advertising Practice (CAP) and the Broadcast Committee of Advertising Practice (BCAP); as well as the advertiser representative on the levy body – the Advertising Standards Board of Finance (ASBOF).
